0.5L Mini Scuba Tank of DOT Certification,Reusable Diving Tanks,5-10 Minutes Scuba Diving Gear,Dive Within 30 Feet Scuba Tank Kit,Portable Backup Air Tanks

The tanks will not fill without the washer popping. Anything over 1000 pops the washer and it doesn’t hold air anymore. Really disappointing as this was a present for my son at Christmas and he is finally going to use it and it doesn’t work at all!

Great for someone that lives on the coast like myself. We are always on the beach & always in the water. This is absolutely a great tank for SHORT dives in SHALLOW WATERS ONLY!Easily accessible & very portable. Space saving.

I have yet to try this for scuba diving, but I have tested it out by filling it up and breathing through the apparatus. The only reason I am only giving it 4 stars instead of 5 is because the instructions are pretty horrible and hard to understand. It comes with extra parts that I think are for changing out parts as you have issues, but the directions don't really explain it well at all. The instructions come in a mixture of Chinese and English but are just hard to understand. It does seem to work well, and the quality seems good. I would/will definitely buy it again. I am very seriously considering buying another just because they do seem to run out of air pretty quickly based on me trying it on dry land. I think this is great for snorkeling when you want to mix in a little diving. Cool little gadget. I should note that I am a certified diver, and I would only recommend this for someone with experience.

Don’t waste your time or money. Pumped this tank for 3 hours with no results. Completely ruined a trip for me.

There’s no information on what to do with all the gaskets, fittings, filters. And once assembled, based on educated guesses, no signs of air pressure after what seems like hours of pumping with the high pressure pump. Worst still the exact tank and kit seem to have disappeared from Amazon completely. Whatever happened to consumer protection at Amazon? Don’t risk $270 down the drain on any of these small tanks!

The quality of this scuba tank is very nice. I haven't been to the dive shop yet to have it filled but am very impressed with this tank. I always watch my oxygen while diving but emergencies can happen as I have been diving with people who run out. This tank is going to be a great backup to have on me. Or I will take it down while reef diving. Overall a very nice tank.

I found this tank to be of good quality and resistance.includes case and other accessories.It requires a PCP Air Pump High Pressure Hand Pump not included for air recharging.I liked it.
